Title: Desizing textiles with bacterial alpha-amylase - at room temp. under mildly alkaline conditions
Inventor: RIZZARDI ANGELO
IPC: D06L1/14
Filed: 1978-08-21
Abstract: Method for removing size from textiles comprises treatment with a bacterial gamma-amylase (I) at room temp (pref. 20-25 degrees C) under mildly alkaline conditions (pref. pH8-10). Desizing agent contg. bacterial (I) is also claimed. Desizing is carried out under mild temp and pH conditions and the time required can be cut by half. Where the size inlcudes polyvinylalcohol or carboxymethylcellulose as well as starch, the size layer is simultaneously swollen which facilitates rinsing out.

Title: Hydraulic drive for HV power circuit breaker - has piston in cylinder operated by pressure medium controlled by piston-like valve
Inventor: BEIER HELMUT ING GRAD
IPC: H01H33/34
Filed: 1978-08-30
Abstract: The drive has a piston in a cylinder, with the force of an energy store continuously applied to its one side. Pressure can be applied to its other side through a pipe and the corresponding cylinder space, or it can be removed from it. The cylinder space can be connected to a low pressure space through a valve whose piston-like body is controlled by the pressure medium in the pipe. The valve (11) has a by-pass (14) connecting the pipe (10) with the cylinder space (9). The flow resistance through the by-pass (14) is greater than the flow resistance to the valve body surface facing the pipe (10).

Title: Gear type hydraulic pump or motor - has axial ends of gears slanted to produce hydrodynamic lubrication of end face
Inventor: GRABOW KURT
IPC: F04C2/08
Filed: 1978-11-03
Abstract: The machine has two gears (12) meshing within a casing. The bearings for the shafts are in bushes between the gears and the endplates of the casing. The bushes are pressed against the end faces of the gears to provide correct axial location. The end face of each gear is cut at a slant so that a wedge-shaped gap (S) is formed between the end of the gear and the face of the bush. The wedge shape widens in the direction of rotation of the gear. This results in hydrodynamic lubrication of the axial end of the gear with reduced friction and wear.
Patent DE-2853396-A1 (DE)
Inventor: GIGER URS
IPC: G04C15/00
Filed: 1978-12-11
Abstract: A stepping motor particularly intended for electronic watches comprises two poles connected to a core bearing an elongated coil. The poles are joined at nose portions thereof by interposed elements of a material having a magnetic permeability as close as possible to 1. The one-piece stator may be formed by blanking from a composite band, thus considerably simplifying the problem of positioning the poles of the stator relative to the plate of the watch movement and to the rotor. A method of fabricating the one-piece stators efficiently consists in rolling together two strips of ferromagnetic metal and an interposed fillet of non-magnetic metal, these elements being joined at their edges to form a composite band from which the stators are blanked.

Title: Increasing filter plate clearance space - by swinging pressure unit completely out of alignment with plates
Inventor: HOEFNER KARL ING GRAD
IPC: B01D25/19
Filed: 1979-06-13
Abstract: In a horizontal filter press with two vertical supports and a head-plate between the supports which during filtering is pressed against the series of filter plates, the pressure-applying unit is entirely disposed between the head plate and one of the supports and is attached to a lever which can be pivoted to take the pressure unit into a rest position which leaves entirely free the gap between that support and the head plate. The pressure unit can be rotated about a longitudinal axis running parallel to itself, or about a transverse axis. The ratio of the space obtained for the removal of cakes to the total length of the press is higher than with known systems.

Patent DE-2930522-A1 (DE)
Title: Sepn. of sulphur di:oxide from gas stream - using successive condensn. stages followed by separators and a scrubber for the tail gas
Inventor: LANG UDO DIPL ING
IPC: B01D53/50
Filed: 1979-07-27
Abstract: Sepn. of a gas mixt. contg. mainly SO2 with a more volatile gas is achieved by multistage cooling. At each stage some SO2 is condensed out and the resulting mixt. is passed through a separator. The gas stream is then passed on to another cooler. After four stages, the liq. SO2 is collected into a single stream and passed through a final separator. The liq. SO2 is run off as prod. while the tail gas streams are combined and fed to a scrubber. Liquor from the scrubber is transferred to a stripping column to remove SO2 and return it to the condenser system. The process recovers liq. SO2 from a mixt. with a more volatile component and combines greater effectiveness with lower operating cost.

Alternatively, the wick section may be contained within a tube, e.g. a polyethylene straw, from which the tips project. The soln. components and element may be packaged as a kit.
Patent DE-3006626-A1 (DE)
Inventor: KRAEMER HORST DIPL PHYS DR
IPC: G01N27/72
Filed: 1980-02-22
Abstract: The invention relates to a method permitting the magnetic properties of ferromagnetic powders which are used for the preparation of heavy media for the float-sink dressing of minerals, to be tested. To this end, the invention provides for the ferromagnetic powder to be magnetized in a magnetic steady field at a field strength within the range 600 to 1000 amperes per cm and the magnetized ferromagnetic powder to be demagnetized in a cyclicly decreasing magnetic alternating field at a field strength within the range 1000 to 1500 amperes per cm. Next, the ferromagnetic powder so pretreated is heaped up, in the center portion of a circular plate made from dielectric material and the circular plate is placed on an iron core-provided coil. An alternating current voltage of 180 to 260 volts is applied to the coil, thereby effecting the occurrence of alternating fields of 180 to 220 amperes per cm in the center portion of the circular plate. The ferromagnetic powder heaped up is observed for the figure it is forming under the influence of the alternating fields. The formation of a closed figure around the center portion of the plate indicates unlimited qualification of the ferromagnetic powder for use in a heavy medium suspension.

Title: Measuring relative orientation of vehicle body and axles - using axle sensors with associated pressure sensitive indicators
Inventor: SUEDBECK RAINER DIPL ING
IPC: B60G17/033
Filed: 1980-04-03
Abstract: The appts. is for determining the relative orientation between a vehicle body and several axles and contains axle sensors and a logic element combining their output signals. It is an economical system enabling load and orientation conditions to be determined simultaneously using only one sensor per axle. A rear axle sensor for modulation of the press proportional to the stroke is connected in series with a front axle sensor for producing a pressure signal proportional to the stroke differential of the two axes or to the orientation. Two pressure sensitive indicators are used. One shows the pressure at the rear axle sensor. The other shows the difference between the axle sensor output signals. The orientation proportional signal can be used to control the position of a head lamp.

Title: Overload protection circuit for electromotor - uses heat dissipated by parallel resistor to melt solder holding supply spring closed
Inventor: FLIEGE HANS ING GRAD
IPC: H02H7/085
Filed: 1980-08-11
Abstract: The overload protection circuit has a resistor (R) connected in parallel with the motor (M). a brake is left in the supply line leading to one end of the parallel combination. The break is bridges by a spring (4) soldered at one end to the supply line on the circuit board and soldered at the other to one end of the parallel combination such that it lies in thermal contact with the resistor. Hest evolved by the resistor during overloading melts the solder and allows the spring to jump open thereby interrupting the supply. The advantage lies in simplicity.
